Thesis Statement Of Dynamite Fishing

Coral reefs not only protect coastlines and beaches from wave damage and erosion, but also are the basis for the fishing and tourism industries. Dying reefs is a worldwide problem, and evidence shows that 10% of the entire world’s coral has died, and 60% will die by 2020 if existing conditions continue (NOAA 2000). The reason that the Australian Great Barrier Reef is so important is because not only is it the largest barrier reef in the world, but it is also one of the most evolved models of how to best manage and protect the world’s largest reef system (Ornitz 1996). It extends for 2,340 kilometers (km), covers 345,000 square km and contains 2,900 reefs, 300 coral cays and 600 continental islands (White 1999). Historically, it has been ahead of the rest of the world in terms of recognizing and addressing problems associated with reef degradation.

Consisting of less than 1% of the world oceans, the coral reefs are ancient animals comprising of thin calcium carbonate deposits within the photic layer. Aside from its biologically diverse ecosystems, coral reefs are major source of food for millions and provides habitats and nursery areas for many marine organisms. Coral reefs also act as a physical buffer to protect the coastlines from tropical storms and erosion. In addition, many local communities rely on coral reefs to generate an income through activities such as fishing and diving. However, 75% of the coral reefs are under threat from induced impacts of humans and climate change (Burke, et al., 2011). This essay looks at the human impacts constantly being inflicted on coral reefs.

The earliest accounts of overfishing occurred in the 1800s, when the demand of whale blubber nearly wiped out the whale populations. In the mid 1900s, the harvesting of Atlantic cod, herring, and California sardines drove them to the brink of extinction. These high disruptions cause regional depletions of animal resources which is starting to cause a global problem. There has never been a more urgent time for fishing nations to make a commitment towards the sustainability of our oceans. More than 80% of the world’s fisheries have been, or are being pushed beyond their limits and are in dire need of strict management plans. Populations of fish and elasmobranch fish such as tuna, grouper and sharks have been declining to the point where the survival

Located in tropical ocean waters, coral reefs provide priceless resources to both human and marine life. The leading natural cause of destruction among the coral reefs is global warming. Other natural causes are earthquakes, hurricanes, cyclones, and typhoons. The destruction to the coral reefs from these natural disasters is minimal compared to the dangers caused by man. Man-made destruction has a much wider impact on the health of the coral reefs. This destruction includes over-fishing, damage from anchors, aquarium industry, overgrowth of seaweed, and being smothered by sediments.

Fishers in the Atlantic Ocean seem to not care at all about the well being of the environment and they care more about the quick catch as I like to call it. The quicker the catch the faster the cash is filling selfish, greedy fisher’s pockets. They are willing to go to great lengths to get the fast money regardless of the lasting damage they cause. It all comes down to their bad fishing techniques. Bottom trawling is a good example of this. They make trawls with large rubber tires or rollers and they help for the net to move over the rocky regions and coral reefs of the ocean floor (Fishing Problems: Destructive Fishing Practices.) These trawls literally destroy homes for fish and make it nearly impossible for them to recover (Fishing Problems: Destructive Fishing Practices.) In fact, 4km of scars on the reefs of the north-east Atlantic Ocean have been found (Fishing Problems: Destructive Fishing Practices.) Dynamite fishing is the next bad fishing technique used. Okay, let’s just take a moment to think of how bad “dynamite fishing” sounds in and of its self. I think we can all understand what type of damage this does not only to the sea life, but to the environment. They literally kill all the fish and wait for them to float to the surface so they can easily scoop them up (Fishing Problems: Destructive Fishing Practices.) They must not be thinking with any foresight because the destruction that fishing like

These three factors, being human impact (pollution/ overfishing), climate change (water temperatures), and natural disasters (hurricanes) play their leading role over the loss of coral reef ecosystems— where reflections such as disease and bio erosion act as the result. The importance over marine biologists, and their conveying message to save the coral reef ecosystem, is a demanding change of our standardized way of life. The science and understanding over this ecosystem can, in good faith, stem a positive human response instead of a negative impact; where through these studies, the public may become aware of the issue and be attentive towards a possible

Of those threats, climate change is the one that has the biggest impact on the reef. The rising temperatures are causing bleaching.When water is too warm, corals will expel the algae, called zooxanthellae, living in their tissues causing the coral to turn completely white (NNOA). Without it, the coral starves, but doesn’t have to die. It can recover from this, but has a higher fatality rate than corals who didn’t go through the bleaching process. The poor water quality is a result of increasing sediment, nutrients and contaminants entering coastal waters in run-off from agricultural, industrial and urban land uses (“Poor Water Quality”). The nutrients and sediments boost algae growth, which effects the corals growth. Overfishing is the final major threat. Once the fisherman catch most of the fish in the area, they must go lower. This leads to them hitting the coral and causing further damage. Although they have these threats, they can overcome it to continue to

Commercial fishing has a great affect on the marine life for many reasons. Those reasons include species of marine life going extinct, or over population. Some marine life are going extinct from overfishing because as scientists said fish are able to produce only a limited quantity of fish over time this problem cannot only affect the fish but it can affect the entire ecosystem in the ocean. Some species of fish are also going extinct from bycatch. Bycatch is when other species of fish or marine life is captured in the nets with the target fish that is supposed to be caught. It is estimated by scientists that 25 percent of the commercial fishing industries around the world harvest is discarded bycatch. Some species of marine life cannot only go extinct but it can also overpopulate. Certain types of marine life can go extinct because their predators are going also going extinct. This issue arose in the early 1900s when commercial fishing industries expanded their fishing fleets.

So what are we supposed to do let them keep injuring other people. But others say that they take away algae and plankton. Is that really worth all those medical bills of broken bones, concussions, and black eyes. Also some people say that they are great for the fish market because of the abundance of them. Brought to you by the U.S. Department of the Interior, “they may negatively affect the area's $7 billion/year fishing industry”. Try to compare a measle 10,000,000 dollars to 7,000,00,000 that is 700 times that amount.

Fishing is a great hobby for the “average Joe.” People fish for fun, family bonding, and to make a living. Overfishing, defined as excessive fishing to an extent, damages local ecology. “Overfishing.org”, found at, http://overfishing.org/pages/what_is_overfishing.php, states, “Catching too many fish; fishing so much that the fish cannot sustain their population”. This means that too many fish are taken out of the water too quickly causing a low population count. People who are overfishing oceans, lakes, rivers, etc. are affecting local biological organism and humankind itself. Humans constantly fishing these bodies of water affect the whole food chain. In a few years, your favorite fish may not exist. World powers, such as the United States

There are many issues but one of the issue is that it attracts sharks into our popular beaches along the south coast. Because we are feeding the tuna Chum, which is small little fish. The problem is that it will affect our Tourist,

Coral reef ecosystems around the globe are threatened by human interferences and climate change. This has led to many scientists conducting studies on global coral reef ecosystems to gain a better understanding of the cause and effects of coral reef damage. In both Hodgson’s (1999) and Carpenter et al.’s (2008) studies, they are aware of the continuous degradation of global coral reef ecosystems. Hodgson's study involved conducting a survey on global coral reef ecosystems to see whether human actions were affecting the health of supposed pristine Coral reefs. Carpenter et al. incorporated Hodgson’s study into a compiled study about the possible extinction of reef building corals due to climate change and anthropogenic effects. Carpenter’s

“Coral reefs are extremely important for biodiversity, providing a home to over 25% of all marine life. They are also vital for people and business. They provide nurseries for many species of commercially important fish, protection of coastal areas from storm waves, and are a significant attraction for the tourism industry”

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the

The deterioration of coral reefs is mainly linked to human activities – 88% of coral reefs are threatened through various reasons as
